iVEDiX interview questions

I had submitted my resume to Ivedix and they were interested in my background in mathematics. I had a very informal interview and was offered a position working under the chief data architect. We discussed salary and start date in person. I was thrilled, having landed a job right out of school. As time passed, I never received a formal offer letter. I tried contacting Raj Kutty, the CEO, about a start date and other details. He would not return my calls or emails. Two months after interviewing, he sent me an email saying he no longer could hire me. They screwed me over, that's for sure.
